A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. People with jet lag may feel extremely tired for several days. They may also have problems thinking clearly and remembering.

Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty young women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights The other half spent more than fourteen days in their home areas.

The researcher took some saliva from the women's mouths to measure levels of a hormone(荷尔蒙) that increases during stress (紧张). He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain's temporal lobes (脑叶).

It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.

The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.

Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently (永久性的) affect memory.

According to the text, jet lag _________.

A. can cause difficulties in speaking

B. the women who fly in short time have smaller right temporal lobes

C. the women who have longer flights fail the memory test

D. the women who rest more than 14 days produce less hormones

What is the subject discussed in the text?

A. The cause of jet lag.      B. A story of a group of flight attendants.

C. The importance of having enough rest after flights.

D. A research about the effects of jet lag on the brain.

A new study by Penn State College of Medicine research team found that honey is a better and safer treatment for children than cough medicines.

   Ian Paul, the study’s lead researcher, was motivated to test honey because treating coughs in children has recently become a sticky subject. Coughing is the body’s way of cleaning irritated (受刺激的) airways to help you breathe. But too much coughing can irritate your lungs and throat even more. It can also make it tough to get the sleep your body needs to heal. Hoping to ease the suffering of their children, parents often give them cough medicines.

But there have never been any good studies showing that they work. Cough and cold medicines may also cause serious side effects. Hundreds of kids die in the hospital each year after receiving too much cough medicine by mistake. Last October, the US Food and Drug Administration suggested that parents should not give cough medicines to children under 6.

In order to search for a different solution, Paul designed a study that involved 105 kids who were sick with coughs and other cold conditions. At bedtime, the kids took buckwheat(荞麦) honey, honey-flavored (蜜蜂味的) DM (one of the most common ingredients成分in cough medicine), or no treatment. Parents and kids in the no-treatment group knew they weren’t getting anything, but the other two groups weren’t told which treatment they were getting.

The surveys showed that kids who swallowed about 2 teaspoons of buckwheat

honey before bedtime coughed less and slept better than kids in other groups.

“When parents want something for their kids to take,” Paul says, “honey seems

 like the best option.”

But what gives honey its healing power? Substances called antioxidants(抗氧化剂) may be part of the answer. All honey contains antioxidants that protect our cells from damage. Studies show that antioxidant levels in the body rise after someone swallows honey.

Which of the following can be the best title for this passage?

A. Sweet solution to kids’ coughing

B. No cough medicines to children

   C. Best treatment for your cold

   D. Cough medicines don’t work

We can learn from Paragraph 2 that coughing ______.

   A. can cure lung and throat diseases

   B. is more harmful to children

C. sometimes does good to people 

   D. helps improve children’s die

During Paul’s experiment, the kids who received treatment __________.

   A. seemed much worse than before

B. had no idea what they swallowed

C. knew they weren’t getting anything

   D. coughed less and slept better

According to the passage, Paul’s experiment proved that ____.

A. honey may have real healing power

B. cough medicines may cause side effect

    C. cough medicines don’t really work

D. buckwheat honey contain more antioxidants

Less educated and less poised（沉着的）than his brother William, Britain’s Prince Harry has occasionally found himself on the front pages of some tabloid (小报) for the wrong reason. Harry has admitted drinking underage and smoking marijuana（大麻）in the past. In January 2006, he apologized after being pictured at a costume party dressed as a Nazi. But one thing he has been serious about is going to Iraq to fight with his fellow soldiers. After completing training last year, he demanded a chance to serve.

As a child he collected military toys and his bedroom walls were covered with posters of helicopters and tanks. Despite his youth, the army has always held a special place in his heart.

 “There’s no way I am going to sit back home while my boys are out fighting for their country,” he said in an interview to mark his 21st birthday. “That may sound patriotic（爱国的）, but it’s true.” Perhaps this shows new strength in him.

Britain’s Defense Ministry announced last week that the 22-year-old Harry would serve a six-month tour of duty in southern Iraq.

Harry said he was “over the moon” and has insisted he wants to be treated the same as any ordinary soldiers.

In Britain, British Prime Minister Tony Blair described Harry’s decision as in keeping with his character. But in Baghdad, Iraqis described it as a public relations move.

Harry has been the focus of attention in the past few years probably because of________.

A. the identity as a prince of the UK

B. his bad habits and wrong behavior

C. his devotion to his country

D. his preference to the army

By saying “Perhaps this shows new strength in him.”, the author means that Prince Harry changed his image by_______.

A. taking an interest in military   

B. apologizing for a Nazi uniform  

C. being willing to serve in the army in Iraq 

D. defending Britain against attack

The underlined word “over the moon” in the Paragraph 5 means_____.

A. very pleased   B. very sad    C. very frightened   D. very calm

Which of the followings is NOT the reason why he insisted on serving in Iraq?

A. He was more or less affected by his childhood’s interest

B. He has grown up and felt a sense of duty to his country

C. His strong character contributes to his decision

D. He wants to make up for his wrong actions

In Iraqis’ eyes, Harry’s decision to serve in Iraq is_______.

A. patriotic     B. political          C. friendly          D. personal

A study of English learning problems was carried out among a total of 106 foreign students. It shows that most students considered understanding spoken English to be their biggest problem on arrival. This was followed by speaking. Writing increased as a problem as students discovered difficulties in writing papers that they were now expected to hand in. Reading remained as a significant（显著的）problem.

The information gained helped us in determining where special attention should be paid in our course.  Although many students have chosen to join the course with a reasonable motivation（动机）, we considered it important to note what seemed to encourage interest. Nearly all the students have experienced some kind of grammar-based English teaching in their own country. To use the same method would be self-defeating because it might reduce motivation, especially if it has failed in the past. Therefore a different method may help because it is different.

Variety of activity was also seen as a way of maintaining（保持）or increasing motivation. Several years ago we had one timetable that operated throughout, but we soon found that both the students and the teachers lost interest by about halfway through the ten weeks. This led us to a major re-think, so finally we brought it into line with the expressed language needs of the students.
